Evaporative cooling common issues and problems


When the cooling is first turned ON, there will normally be a delay before the cool air is delivered from the duct outlets. The delay will vary depending on the cooler's brand/model, but this doesn’t mean the cooler is not operating. Most coolers have pre-programmed delay times to fill up the Cooler’s tank with water and/or Pre-wet the filter pads. The entire process can take up to 10 minutes before cool air is expected from the duct outlets.

Shut down

Many modern cooling units fitted with a dump valve, there is also a delay in emptying the water from the Cooler’s tank for a period after the unit has turned OFF at the end of use. Some models have an additional pre-programmed tank wash cycle. This washes the tank with clean water at the end of use.

If you’ve noticed that it takes Cooler too long to Startup, or it’s continuously leaking water outside of operating cycle - might be there is a problem, and it’s a good idea to get it checked by a Licenced Technician.

Evaporative cooling common issues and problems

Q. How often should the cooler be serviced?
A. All manufacturers recommend servicing cooler every 2-3 years to ensure it operates at peak efficiency. Maintenance recommended being performed before the summer season to keep cool and comfortable through the summer months.

Q. The air smells a little different. Why?
A. The brand new cooling pads can give off a mild odour while they are settling in. However, if cooler is a few years old, it may be indicating that the unit needs a thorough clean and check.

Q. How much water does my evaporative cooler use?
A. The amount of water an evaporative cooler uses is dependent on the evaporation rate of the coolers pads. On a hot day, the cooler may refill every half an hour.

Q. How many doors and windows should I have open?
A. Evaporative cooling relies on doors and windows being open, so you need to provide the minimum required airflow relief area. Refer to the owner’s manual for exact numbers. The Rule of thumb is at least one door and window must be open.

Q. Why is there condensation and moisture on my tiles and furniture?
A. If condensate is forming on a hard surface while the evaporative cooler is ON, first of all, make sure a sufficient number of doors and windows are open. Check that the vents are directed across the room and not towards the floor. Also, ensure the unit and filter pads are clean and free of debris.

Q. Is Evaporative cooling effective? How cool is cool?
A. The degree of cooling available from any air conditioning system, is dependent on the outside weather conditions. Evaporative Cooling works best on hot, dry days. If the unit is clean and functioning correctly, you should expect the temperature difference of at least 10 Degrees Celsius.

Q. Should water be coming out of my evaporative cooler during operation?
A. Modern coolers shouldn’t leak any water during operation as they have an Auto Drain Valve fitted. Some models will complete a flush service approximately every 20 cycles. Also basic or older Cooler models have a “bleed-off” system installed and will discharge a small continuous flow from the drain outlet while the pump is ON.
